Application iiled October 29, 1921;

To all whom t may concern Be it. known that We, JOHN lll. Vnnnnn andllnnnnnrcii lll. Lonnrne, residents of llforcester, Massachusetts, andcitizens 0i have invented new and useful Improvements in Paper-MakingMachines, which invention is fully set forth in the followingspeciiication.

This invention relates to the Fourdrinier or Wire part of papermachines. ln niany mills. in the Inalring of news print paper (which maybe of low grade or quality because it is only ior temporary use) it iscommon practice to dispense entirely with shaking of the Wire. But lorhigher grades olf' paper the usual lateral shaking ci the Wire is stillresorted to by the use of structures in which the shaking or vibrationis imparted to a, longl and heavy itraine, to the breast roll, numerousWire supporting table rolls, guide rolls and other parts all mounted onsaid iranie, and to the Wire itself running; over said rolls, saidshaken parte gregating great mass and Weight The repeated starting andstopping;` oif such inass and Weight of parts, ence for each vibration,involves great strain. requires additional Weight to attain requisitestrength oi structure, occasions considerable Wear and deterioration oi" parts with resulting` increase in cost oi maintenance or upkeep. andalso occasions complications @i parte and structure addingl to the timeand ei'lort required in replacements oi? the vvire7 each Wire lastingonly i'roi'n one to three Weeks in a machine running regularly at normalcapacity. ln such structures the iull length oif the lateral 'l king'stroke imparted to the end oi' the rame at which the breast roll`carried, grraiflually diminishes in amplitude toward the other end orthe traine which pr, turns about or pivots on a rertii i While the inl1force and width oi' the shaltinf Stroke at and in the Vvicinity of thebreast roll is desirable and necessary to thoroughly interweave thefibers ot the pulp mixture delivered on to the Wire, the attenuateddiminution in amplitude of stroke until it becomes practically nil atthe far end Serial No. 511,340.

of the long vibrating trame and long series of table rolls carriedthereby, acts to a material extent to straighten out the libers of thesheet and to thus undo the previously attained intervveaving of saidfibers. ln other Words, appr ximately as goed and possibly better paperformation may be attained by shortening the shaking length oi Wire.

rlhe primary object or' this invention is to provide a machine in Whicha relatively short length of Jhe wire at the receiving end thereof Willbe shaken or laterally vibrated to avoid attenuated gradual diminutionop." shalt@ or vibration elitenoing far down the wire from thereceiving` end thereoif, and to accomplish this in a manner dispensingwith large and Weight oi shakparts and eliminating strain and rapid tothus simplify' the mechanism and e ct a material. saving; not only inthe initial cost thereoiFl but in expense o'f main-- tenance or upkeepolf appar tus.

Referring first to Figs. 'l to 6 'inclusive-to provide for changing theelevation ot the Fourdrinier Wire at the receivingI end thereof and totliereby Aattain the desired piteh or inclination oit' said wire 'fromits` receiving toward its delivery end, We, employ a traine carryingmost ot the rolls on which the Wire runs, said -Atrarne being;rvertically adjustable at its end toward the tloiv box and supported atits other end 'to turn on a horizontal axis or pivots. Said trame ismade up of the folio-.ving partsat the end thereot next tothe ilovv boi;there is a 'transversely positioned beam il -o't elongated U-shapelhaving1 at its opposite ends respectively upstanding l2 and 13 ofhollow construction. lil is a longitudinally extending -top rail at oneside oit the frame secured at one end by bolts l5 to the top of arm 1 3of beam ll and cured at its other end by a bolt 16 to a plate 17 whichfits on a block 18. said block depending between tivo ears lil and l?)at the upper end of a supporting post or standard 20 and said ears andblock heine; traversed by a horizontal pivot pin Q11., such structurebeing;` similar to that illustrated in Figs. 6 and 7 olf Patent No. 1,1,366, dated Nov. 24, i914, to Mellinger, et al.

A. fiat steel spring har 48, the right hand side et the machine, Fig. 2.is securely bolted at its upper end in a slot `oit a link e9 the beivg;pivoted by a pin 50 in a slot be- -llll ien tween ears 5]. (F ig. 7 onthe underside of the bearing member 46; but it preferred said upper endof the spring may be rigidly secured to bearing member 46, for example,in the manner the upper end of the corresponding spring of the aforesaidMellinger et al. patent is secured. Said spring 4S at its lower end isseated in an upwardly opening notch or slot 52 of a stirrup or bracket53, Figs. l, 2 and 5, depending from and preferably cast integral withthe upright arm 13 of the beam 1l. By such arrangement said bearing 46is movably supported by the spring 48 with the flat surface 54, Fig. 7thereof in engagement with a bearing plate 55, preferably of brass,which as shown in Fig. 5 may be detachably secured to the arm l2 byscrews. The other bearing member 46 at the other side of the machine, atthe lett in Fig. 2, is supported by similar means including a fiat steelspring 56, link member 57, pivot pin 58, a notch or slot 59 engaged bythe lower end or" spring 56, said notch being formed in a stirrup orbracket depending from arm l2 of the beam ll. In this instance also aiiat face 54 of the bearing member 46 engages a brass plate detachablysecured to the arm l2 and similaito the plate 55 hereinbefore described.The projecting end ot the pivot pin 58 is engaged by the end of a pitmanor connecting rod 6l, Fig. 2, driven from any suitable source of power(not shown) to impart vibrating or shaking movement to the bearingmember 46 at the left of Fig. 2 and thence to the breast roll 45 andthrough it to bearing member 46 at the other side ot the machine. An arm62, secured at one end to the bearing member 46 at the lett in Fig. 2 bybolts 63, bends rearward to a p ivotal bolt connection at G4 to theforward end of the hereinbeiiore described angle bar 4l, said arm thusserving both to support said end of bar 4l and to impart vibrating orshaking movement thereto around the pivotal support at the rear end ofsaid bar. An arm at the right of Fig. 2, similar to 62, secured by bolts66 to the bearing member 46, also bends rearward to a pivotal boltconnection at 67 to the 'Forward end of angle bar 40 hereinbe foredescribed, said arm 65 thus serving both to support said end oil.L bar40 andto impart vibrating or shaking movement thereto around the pivotalsupj'iorting connection at the rear end thereof. Such lateral vibrationor shaking of the bars 4() and 4l, sinn'lltanc ously with the similarmovement ot' the breast roll 45, also imparts endwise shaking movementto the series ot table rolls il een tending between and supported bysaid bars.

To prevent vibration of the hereinbeifore described :traine incident tothe aforesaid. shaking of the breast roll and the series oit table rolls3l. two 'vertically depending plates 70, 70 are secured by bolts to theun' derside of the U-beam 1l, near opposite ends thereof respectively,each plate 70 fitting closely and slidable between the oppositelypositioned vertical surfaces of a pair of brackets 7l bolted to atransverse base beam 72, Fig. 2. Thus while the plates 70 per mitvertical. movement or adjustment of the breast roll end of the 'frame inchanging the pitch of said frame and of the Fourdrinier wire carried bythe rolls thereof, said plates 70 rigidly secure said frame againstlateral vibration incident to the shaking of the breast roll and otherparts.

73, 74, Fig. l and Fig l;L are carrying rolls for the Fourdrinier wiresuitably mounted through the intermediary of suitable bearings (notshown) at opposite ends of said rolls, on the bars 24 at opposite sidesof the machine, or on the iframe ot which said bars constitute parts.76, 77 and 78, Fig. lZL are other carrying rolls for the wire suitablysupported and journaled in well known manner not illustrated. 79 is thelower couch roll also suitably supported and journaled in well knownmanner notillustrated and over which the wire runs at one end of itspath of travel. 8O is the endless Fourdrinier or making wire runningover the aforesaid rolls and passing at one end around the breast roll45, the pull on said wire serving to hold the projecting ends ci theshaft or axle of the breast roll firmly seated in the open sided bearingrecesses of the two bearing` members 46, 4G, respectively.

S1, Sl are two save-all receptacles each extending` across the machinebeneath the table rolls and wire thereon and resting at opposite ends onrollers S2 journaled in supports S3 secured to bar 24 and to thecorresponding bar at the other sideof the machine. Suitably supportedroots 84, each resting at one edge on an edge ot one of the save-allreceptacles 8l, serve the usual pun pose oil draining into saidreceptacles liquid falling thereon from the pulp mixture delivered on tothe wire. These save-all receptacles and roots being thus mounted uponand carried by the frame participate in any vertical adjustment oi saidframe in changing the pitch oi the wire The saveall receptacles androots may however be supported independently ot the trame so as not toparticipate in adjust-ments thereof.

Vertical. adjustment of the breast roll end of the aforesaid frame iseffected by the 'ich lowing means z--The ujiright arms l2 and i3 of theU-beain ll are each formed with downwardly opening socket 85 having abearing block 86 of hardened metal secured in the upper end thereof andprovided with a downward opening seinispherical bearing recess orsocket. A tubular supporting member 87 extends upwardly into said.socket 85 and has secured to its upper closed vend a bearing block 88 othardened metal l tl having4 an upwardly projecting semispherical knobengaging the corresponding socket ol' block 80, as best shown in Figjl.Art its lower end the member 87 rests and is held by the weight ot partsina seat 89, 4, or' a casing,` toi-ined in two parts 90 and 91detachably held together by bolts 92 and serving to enclose antiirictionball bearings and gears about to be described. An upright support, post,or bar 95 is horizontally pivoted at its lower end at 96 in a base block97 rigidly secured to the floor or other foundation on which the machinemounted. The upper screw-threaded end of har 95 extends upward throughthe two part casing;` -91 and 'nto the tubular member 87, as best shownin Figs. 1 and 4. A worm gear 98, housed within the two part casing):-90--91.y has an elongated interior screw-threaded hub through which thescrew-threaded portion ol? bar engages. Three sets of antifriction orball bearings, shown in 4, are interposed between the worm gear 98 andits two part enclosing casing,` to take the vertical and side stressesot' the supported load and to provide ttor tree and easy rotation ofsaid worm gear in raising or lowering` the trame and parts carriedthereby to change the pitch of the wire. The balls 100 of the lowermostset oi: bearings work between a ring 101 surrounding the lower end otthe hub oit' the worm gear and a ring 102 secured within the casingmember 91. An annular plate 103 is secured by screws to the underside o1casing 91 and carries a packing` ring` 104 of leather or other suitablematerial closely itting around the peripheral surface o1 the lowerextremity oit the hub on the worm wheel to prevent leakage of lubricant.The balls 105 oi the next set oit ball hearings work between a ringw 106surroundingthe part of the hub projecting upward from the top side ofthe worm gear and a ring 107 secured in the upper casing member 90. Theballs 108 of the uppermost set ot ball bear ings, which set takes thestress of the vertical load, work between a ring 109, located .at thetop of casing` member 90 and surrounding the upper end of the hub ofworin wheel 98, and a ring 110 also surrounding, said upper end or" thehub and separated from the before mentioned ring 106 by an interposedring` 111. A worm 112, also housed within the-two part casing 90-91,engages the worm wheel 98 and is secured to a horizontal shaft 113 whichhas bearings in said two part casing;v vat opposite sides of said worin.Said shaft 113 extends all the way across the machine and kcarries ateach end thereof a hand wheel 114 as best shown in Fig. 2.

It is to be understood that the tubular support member 87, the two partcasingu .904491, the upright .piroted screw-threaded cated at the otherside oit the machine in connection with Jhe upright arm 12 and itsdownwardly opening,- socket, the: shai't 1.13 being common to the twoworms 112, 112 at opposite sides ot the machine. AS will thus beapparent, rotation of said shaft by gripping; and turning .either ot itshand wheels 114, acting through the two worms 112, 112, on said shaltwill rotate the two worin wheels in engaementv with thetwoscre-w-threaded support bars 951 at opposite sides ot the machine andthereby raise or lower the supporting traine iiinitornily at both sidesoi? the machine according; to the direction in which the hand wheel 114is turned.

Referring particularly to Figs. 1 and 1a, is a deckle strap running overa deckle wheel 121 at one end, Fig. 1, and deckle pulley 1.22 at itsother end, Fig. 1, and passing through deckle wash trough 128 supportedon a deckle trame 124 shown as supported from the side rail 14 bybrackets 125, 125, all these parts being or well known construction andduplicated at opposite sides of the machine.
